چکیده    In this study, it is aimed to determine the effect of increasing nitrogen doses (0, 5, 10 ve 15 kg n/da) on some agricultural characteristics at durum wheat cultivars (levante, zenit, yelken 2000, dumlupınar, eminbey, altın, çeşit-1252 ve kızıltan-91) in isparta conditions.in this research, the nitrogen doses had significant effects on investigated characteristics (plant height, number of spikes per square meter, number of seed per spike, biological yield, harvest index,). on the other hand, the effect of nitrogen fertilization showed significant differences according to varieties (except of plant height and number of spikes per square meter). according to the variety used in the experiment, the average plant height was varied from 76.97 (levante) to 98.48 (dumlupınar) cm; number of spikes per square meter from 249.40 (levante) to 350.90 (altın); the number of seed per spike from 32.69 (altın) to 43.60 (levante); biological yield from 963.1 (levante) to 1381.3 (yelken 2000) kg/da; the harvest index from 24.29 (dumlupinar) to 30.46 %(levante), yellowberry kernel percentage from 13.5 (altın) to 23.0 % (eminbey).according to nitrogen doses average it was determined that the average plant height 81.12- 87.59 cm; number of spikes per square meter 253.44-365.75; the number of seed per spike 37.23-40.77; biological yield 852.1-1505.0 kg/da; the harvest index 21.36-31.09 %. although nitrogenous fertilization increased yellowberry kernel percentage, this increase was not found to be statistically significant. as a result, it has been determined that nitrogen fertilization is effective on the investigated properties, but it may vary according to varieties.
